1389208 ÷ 245 
The aim is to understand the frequency of 245 in 1389208.

Moving on to step 1:
If we divide 1 by 245, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 245

Moving on to step 2:
245 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 245

Step 3:
When dividing 138 by 245, we get 0 with a remainder of 138.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Take the next digit (9) from the dividend and append it to 138, then repeat: 1389 / 245

Let's proceed to step 4:
245 can be fit into 1389 5 times, resulting in a remainder of 164.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 164 after subtracting 1225 from 1389.
Grab the next digit (2) from the dividend, add it to 164, then carry on: 1642 / 245

On to step 5:
245 goes into 1642 6 times with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 1470 from 1642, we get 172.
Fetch the next digit (0) from the dividend, attach it to 172 and continue: 1720 / 245

Let's proceed to step 6:
245 can be fit into 1720 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 567.0
If we subtract 1715 from 1720, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 245

Advancing to step 7:
If we divide 58 by 245, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 5670.0
Subtracting 0 from 58 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
When dividing 580 by 245, we get 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 5670.2
If we take 490 away from 580, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
245 can be fit into 900 3 times, resulting in a remainder of 165.
Write down 3 as next digit of the result. 
Result so far: 5670.23
If we take 735 away from 900, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
The number 245 fits into 1650 6 times, leaving a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 5670.236
Subtracting 1470 from 1650 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
When dividing 1800 by 245, we get 7 with a remainder of 85.
Record the quotient 7 as the next digit in the result. 
Result so far: 5670.2367
Deduct 1715 from 1800 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
When dividing 850 by 245, we get 3 with a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 5670.23673
The remainder is 115 after subtracting 735 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 13:
If we divide 1150 by 245, we get 4 and a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 5670.236734
The remainder is 170 after subtracting 980 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 14:
245 can be fit into 1700 6 times, resulting in a remainder of 230.
Use 6 as the next digit of our solution. 
Result so far: 5670.2367346
Subtracting 1470 from 1700 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 15:
245 can be fit into 2300 9 times, resulting in a remainder of 95.
The next digit of our result is 9. 
Result so far: 5670.23673469
Subtracting 2205 from 2300 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final result is 5670.23673469 with a remainder of 9.5e-08.
